Description:
Alkali-silica reaction (ASR) causes cracking and with it substantial damages in concrete structures worldwide causing substantial costs due to repair or replacement. Although ASR is one of the major focal points of concrete research since the first cases were reported in the 1940's, our knowledge is still not sufficient to understand various aspects of the reaction. This includes the understanding about various steps in the mechanisms of the reaction, the products formed and damage development. In an ASR-project funded by the Swiss National Science Foundation (SNF CRSII5_171018) multidisciplinary approach was used to study ASR from the nano to the metre scale using dissolution experiments, thermodynamic modelling, structural analysis, 2-D characterization, 3D imaging and computational modelling. Six subprojects were conducted at four different institutes benefiting from the synergistic effects provided by a close collaboration. In the webinar we will present selected highlights of the project.
